Summary

This study tests how different cannabis packaging designs and health warning labels affect people's perceptions of risk and their intentions to use cannabis. Researchers will show adult cannabis users in states where recreational cannabis is legal a series of hypothetical product packages with varying features, such as warning size, branding, and THC content. The goal is to find the most effective combination of packaging elements to clearly communicate health risks and support informed decision-making.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If effective warning labels are identified, this could help regulators design packaging that better informs consumers about cannabis health risks.
What could go wrong: This is a hypothetical online experiment, not a real-world purchase setting, so actual behavior may differ. Results depend on self-reported intentions, which may not predict real choices.
